Firefox 社群討論區

Whenever my laptop starts up,firefox with all of my tabs always starts up with it. When i rose up earlier in the day and started up my laptop firefox with all my tabs opened up as normal,but this evening everything is gone. I had at least 20 tabs open and they were all important. There was no option to recover the tabs and this isn't the first time this has happened,this is at least the third time that this has happened after the last year and a bit. This is incredibly annoying and frustrating. Is there even any point in asking the community how this can be resolved?

Firefox updated automatically. No bookmarks or history??? I cannot find anything. This is my old Windows 10 computer. Have bookmarks on Windows 11 computer. Afraid of updates. any help?

This is the message I get when I try to access my Bookmarks: "The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem." I have already tried to find out from Microsoft if their latest reinstallation of Office Professional could have caused the problem. They say they have nothing to do with Firefox. How can I get my Bookmarks and History back?

I just used CCleaner health check and when done all my bookmarks were gone. I've had CCleaner for years and never had this happen before (laptop). The troubleshooting list was unclear and did not correct the problem.

This morning all my bookmarks have vanished, and I can't recover them using the instructions in the help articles. ALL WERE AVAILABLE LAST NIGHT. My home page is the only thing still there

I recently bough a new computer and transferred all my data, passwords and bookmarks to it. Each time I opened my mozilla browser I was encouraged to create a profile , but each time I just continued without creating a profile. Finally today I was not given an option to proceed without creating a profile so I did. But now all my passwords and bookmarks have disappeared. When I try to find them I am advised to load my previous profile but this is not an option the only profile I have is the one I just created with the missing data. Can you please tell me where the appropiate files are stored and how can I recover them. Thanks

Firefox crashed with many open tabs. I went to History > Recently closed tabs > Reopen all tabs, clicked. Nothing. The list showing only very few of the tabs I had open, but none of them are restoring anyway.

3 times now, my account has completely reset, forcing me to log into everything again and not working with the key that I copy and pasted and downloaded. I would like my old data back. Why does this keep happening?

Hi customer service, please help me to restore firefox data & tabs before today. my firefox update this evening crashed & unable to restore. Million thanks

I updated Firefox to 145.0 this morning, and after Firefox had restarted, it had lost all bookmarks and the bookmarks toolbar. I have spent all day following links to correct the problem and got nowhere. I have restarted Windows and Firefox countless times - no change. I've even tried reinstalling Firefox over the existing version. If I go to bookmarks > manage bookmarks > restore and backup, sometimes that will load, others not. When it does load, it fails to find a file to restore from. 10 years of bookmarks, links & research vanished.

Can someone please provide a solution (preferably in Layman's terms) to this??
